Interference to PCS Channels from SpaceX Tue, Aug 27, 2024

On August 16th, AT&T filed a petition to deny SpaceX's waiver request that would allow SpaceX to operate from space on T-Mobile's PCS G channels.  From the Web Spectrum Viewer map below, it is evident that T-Mobile controls nationwide access to the PCS G channel except for some places in Wyoming, Nebraska, Kansas, and Oklahoma where they are leasing those channels to regional carriers.

Spectrum Depth Map - T-Mobile (PCS-G):

Why is T-Mobile Giving Up Spectrum in Hawaii? Tue, Mar 05, 2024

T-Mobile made commitments to the FCC in the Memorandum Opinion and Order in their application for their Auction 108 (2.5 GHz Band Licenses).  T-Mobile committed to divest by sale or swap, 20 MHz of spectrum in the AWS-1, AWS3, PCS, or 2.5GHz bands.  The spectrum sold will be no smaller than 10 MHz blocks of TDD spectrum or 5x5 MHz blocks of FDD (paired) spectrum.  T-Mobile has twelve months to file the transfer applications.

The FCC specifically called out two CMA markets where T-Mobile will need to divest spectrum:  CMA385 - Kauai and CMA386 - Maui.  Although T-Mobile's held spectrum in Hawaii doesn't stand out compared to other markets in the US, the issue with the spectrum screen in Hawaii is that 3.45 GHz spectrum (100 MHz) and C-band spectrum (280 MHz) are not available.  This reduces the available spectrum by almost 400 MHz, thus reducing the spectrum screen by potentially 126 MHz. 

In the above map, the CMA markets in Hawaii are indicated.  To see how each carriers spectrum totals up in each of these markets we will utilize our Web Spectrum Viewer - Spectrum Depth Module.  First we have exported the county spectrum totals by band classification.  Kalawao and Maui county make up CMA 386 and Kauai county makes up CMA385.  The bottom 3 counties in the chart below represent the counties where T-Mobile needs to divest 20 MHz of spectrum.  

Reviewing the data, it is clear that T-Mobile's lower mid-band spectrum and upper mid-band spectrum are the two areas where T-Mobile has a sizable advantage.  I assume that EBS/BRS spectrum is off the table from T-Mobile's perspective and it would be difficult to sell that band due to T-Mobile's nationwide "exclusive" use.

Looking then at the lower mid-band spectrum, T-Mobile's held spectrum in both the AWS-1 and AWS-3 bands is pretty similar with Verizon and AT&T. 

I will also note that if T-Mobile was to give up any of their AWS-1/AWS-3 spectrum holdings they would drop below their desired 20MHz channel in NR band 66.

There are two considerations for T-Mobile's PCS spectrum.  First, T-Mobile controls two blocks of spectrum in all of the Hawaii counties, 15 MHz at the bottom of the band and 20 MHz at the top.  I believe that T-Mobile's agreement with SpaceX utilizes the PCS G channels at the top of the PCS band, so I think the upper block will be retained.  In a perfect world, T-Mobile would sell a 10x10 slice (A8-A11) of their lower block of spectrum to Verizon and swap their A6-A7 spectrum with Verizon for Verizon's F1-F2 spectrum.  In this scenario, Verizon would increase their channel size in two of these counties from 10/10 to 20/20 and in Kauai they would have 25/25.  T-Mobile would then have all of their spectrum together and could have a NR band 25 - 20MHz channel and a dedicated 5 MHz channel for SpaceX.

Evaluating Spectrum Screens by Band Classifications Tue, Oct 24, 2023

Market Spectrum Screens for the US National Carriers Wed, Oct 11, 2023

The recent news highlighting a FCC proceeding into the spectrum screen referenced, some analysis by Raymond James establishing T-Mobile dominance with 350MHz of spectrum on average in the nation's top markets.

To see how that plays out on a market by market basis, I am going to use the spectrum screen analysis data from Spektrum Metric's Spectrum Ownership Analysis Tool which details the spectrum that applies to the screen for all of the US counties or for all of the US Cellular Market Areas (CMA).  The chart below is for the Top 49 CMA markets by population (2021 estimated population). The markets are sorted from highest population on the left to the lowest population on the right. I have eliminated San Juan, PR because the national carrier's don't have a consistent investment strategy for many of the US territories including Puerto Rico.

A Look at USCellular's Spectrum Ownership in Spektrum Metric's Tabular Views Tue, Aug 15, 2023

Previously we looked at US Cellular's Spectrum Ownership via Spektrum Metrics Map Views.  In this post, we will utilize Spektrum Metrics' Mobile Carrier - Spectrum Ownership Analysis Tool to evaluate how USCellular's low band spectrum will fit with the other national carriers.  In the County Analysis tab, we can see each carrier's total spectrum and the amount of low band spectrum.  In this view we used the autofilters to select only the counties where USCellular has spectrum.  This allows us to see how each of the national carriers spectrum assets compare in the counties where they can acquire spectrum from USCellular.  This view reveals that USCellular has very limited overall spectrum in the largest markets.  They have 20MHz of spectrum in one of the Boston CMA counties, and  12MHz in most of the St. Louis counties.

When we look at the frequency band information in the same analysis tab, we can see the counties where USCellular's low band spectrum includes cellular spectrum.  We can also see whether AT&T or Verizon is missing cellular spectrum in a county where USCellular's spectrum would fill a need.  Cellular spectrum is critical to both Verizon and AT&T because they have anchored their low band 5G coverage on that spectrum.  To evaluate the strategic plan for USCellular's cellular spectrum further, we are going to copy the data from this table into another Excel tab for further analysis.

Next we want to analyze which counties Verizon would like to acquire the USCellular cellular spectrum, which counties AT&T would like to acquire, and which counties they both would want, meaning neither carrier has cellular spectrum.  After determining which counties align with Verizon and those that align with AT&T, we will calculate the MHz-POPs that each carrier would likely  acquire.  When we bring the county data over, we leave the column that includes the 2021 population for each county along with the appropriate spectrum depth columns..  After identifying the counties where there is a clear desire from AT&T or Verizon for the cellular spectrum, we can calculate the MHz-POPs for each carriers desired acquisition by multiplying the population by the spectrum depth in the "New" columns.

In our cellular MHz-POPs analysis, below, subtotals for spectrum Verizon would acquire, AT&T would acquire, and the spectrum that could be acquired by either company are listed.

3.45GHz Auction Results Sat, Jan 15, 2022

On Friday, the FCC posted the results from Auction 110.  On Saturday we updated the January 2021 release of our Mobile Carrier - Spectrum Ownership Analysis Tool to reflect the auction results.  These results provide the most detailed view of each carrier's spectrum that can be deployed for 5G, particularly all of the available upper mid-band spectrum including EBS/BRS, 3.45GHz, CBRS, and C-band.

In the Spectrum Grid, we can see the channel allocations.  In general, Dish took the upper end of the band with T-Mobile and AT&T alternate having the lower parts of the band.  In many markets, AT&T is pinned in the middle of the band between T-Mobile, Grain, and Columbia Capital.  Each of the spectrum investors has selected spectrum assignments adjacent to AT&T's spectrum meaning they are each well positioned to sell to AT&T if the 3.45GHz spectrum cap is lifted. 

In the National Band Ownership slides we look at each carrier's ownership based upon the percent of MHz-POPs that they control.

For the 3.45GHz band, AT&T leads the way with 39% of the MHz-POPs, Dish has 30%, T-Mobile has 12%, and USCellular has 4%.  

Looking the the complete picture for Upper Mid-band spectrum, T-Mobile still leads with 34%, Verizon follows with 30%, then AT&T with 24%.  Dish has 9% of the upper mid-band MHz-POPs and USCellular has 2%.

C-band Interim and Future Licenses Thu, Aug 12, 2021

On July 23rd, the FCC granted most of the C-band (Auction 107) licenses. This provided us the first opportunity to see how the FCC was going to handle the interim A block licenses that will transition into the permanent license on December 31, 2023.  The FCC provided call signs for each of the permanent licenses as well as call signs for each of AT&T's interim licenses.

These interim and future designations allow us to highlight a unique capability of our Web Spectrum Viewer and Mobile Carrier - Spectrum Ownership Analysis Tool.   For each block of spectrum we capture the spectrum licensee and the carrier that may lease the spectrum.  This information indicates the current operator.  Typically the current operator is the future operator, unless a pending transaction allocates that spectrum block to a different operator.  We are using this database capability to reflect the interim C-band licenses with the current operator field and the permanent operator with the future operator field.  You can see the AT&T interim allocations below as we are displaying the "Current" Spectrum Ownership Grid. 

Current View:

The future allocations are seen in the Future View below.

Future View:

Another way that this current and future ownership data can be seen is in our Spectrum Survey.    The Spectrum Survey provides the call sign, current operator, and future operator for all of the frequency bands in a selected county.

5G Reconfiguration in Mexico Tue, May 19, 2020

In April, El Economista highlighted a transfer of 3.5GHz spectrum in Mexico from Telmex to Telcel.  The article highlights a series of consultations between Telmex, Telcel, AT&T, and the Federal Telecommunications Institute (IFT).  I will use our Mobile Carrier - Spectrum Ownership Analysis Tool (MEX) to examine these transactions and the overall 5G spectrum plans in Mexico.

Our Spectrum Grid from December 2019, reflects the ownership of the 3.5GHz band prior to the Telcel acquisition.  At this point, Telmex, AT&T, and Axtel each owned 50MHz of spectrum (25MHz of uplink and 25MHz of downlink spectrum).  In this view we included a TDD band class 48 which is the only band class defined by 3GPP for this band.  Obviously, systems using this band configuration are not using band class 48 since they are FDD and band class 48 is TDD.

AT&T and Telmex approached the Federal Telecommunications Institute (IFT) in December to request that they exchange AT&T's D channel for Telmex's H channel, providing each carrier with 50MHz blocks of spectrum in the 3.5GHz band.  This exchange only makes sense if IFT reconfigured the entire band to TDD spectrum. 

The new configuration is reflected in the image below with Telcel acquiring Telmex's 50MHz channel.  Now Telcel and AT&T are set up with the minimum 5G channel size in one of Mexico's two TDD bands and IFT also has 150MHz of spectrum remaining for a future auction.  It is interesting to note, that both Canada and Mexico have opted for licensing spectrum directly to carriers for their 3.5GHz bands while the USA has gone with the shared spectrum and PAL licensing approach.

Assessing the COVID Temporary Spectrum Licenses Tue, Mar 31, 2020

Last week we began to see announcements from the FCC authorizing a series of temporary spectrum usage agreements to provide additional spectrum to several of the wireless operators to increase network capacity as workers are dispatched to their homes.

We will look at the effect of these agreements in a few markets to see how they are increasing LTE capacity.  The analysis will be supported with outputs from our Mobile Carrier - Spectrum Ownership Analysis Tool  specifically the Spectrum Ownership Grid.

T-Mobile 600MHz Capacity Expansion:

The first agreement provides T-Mobile with access to 600MHz spectrum from Bluewater Wireless, Channel 51 LIcense Co and LB License Co (Columbia Capital), CC Wireless Investment (Comcast), ParketB.com Wireless (Dish), New Level (Grain), and Tstar License Holdings (Tri-Star).

In the image below for the New York CMA market, T-Mobile will have access to Comcast's spectrum (XFI) and Dish's spectrum increasing their 600MHz channel size in New York from 10MHz channel to a 20MHz channel.  T-Mobile would have access to the entire 35MHz of spectrum so they could provide a 20MHz channel and a 10MHz channel for capacity.   Because T-Mobile has already deployed Band 71 equipment in New York, they can turn up the expanded spectrum without additional equipment installations.

USCellular AWS-3 Capacity Expansion:

The next agreement provides USCellular access to AWS-3 spectrum from their bidding partner Advantage Spectrum.  In the image below a few of the Washington markets where USCellular will access AWS-3 spectrum are indicated.  In most of these markets, USCellular currently operates on their cellular frequencies but doesn't have Band 66 operations.Thus,  USCellular will need to add base stations and antennas to their sites for Band 66 to utilize these new frequencies.  In five of these counties USCellular is likely operating on AWS-1 spectrum in Band 66 so the spectrum will be easier to deploy in those counties. 

Verizon AWS-3 Capacity Expansion:

In the image below we illustrate the AWS-3 spectrum that Verizon will gain temporary access from SNR License Co and Northstar Wireless (both Dish partners).  Northstar controls the AWS-3 G channel and SNR LIcense Co controls the AWS-3 H channel.  In the New York market, Northstar Wireless owns the G block spectrum and SNR Wireless owns the H block spectrum.  Accessing this spectrum will provide Verizon a second Band 66 LTE channel, increasing their LTE capacity from 20MHz to 30MHz.

Verizon & AT&T AWS-3 Capacity Expansion:

Verizon and AT&T have also requested access to the spectrum that Northstar Wireless and SNR Wireless returned to the FCC when their auction discounts were eliminated.  The AWS-3 spectrum depth that is "unassigned" is indicated in the map below.  In our data, we reflect these unassigned licenses with the FCC heading.

AT&T requested the I block spectrum in the New York market, so it will expand their Band 66 LTE from 10MHz to 15MHz.  The markets AT&T requested are listed here and the markets that Verizon requested are here.

AT&T AWS-4 Capacity Expansion:

AT&T has also requested access to Dish's Band 66 spectrum.  From the image above AT&T can expand their Band 66 LTE by and additional 5MHz to 20MHz by using part of Dish's AWS-4 spectrum.  AT&T will still have an additional 15MHz of Dish's spectrum that they could use as an additional LTE channel in New York.  AT&T only requested access to Dish's Band 66 spectrum, not their Band 70 AWS-4 spectrum.

AT&T 700MHz E-block Expansion:

Dish also reported that AT&T requested access the the 700MHz E-block in the markets that AT&T doesn't own.  In the image below, Dish's ownership in Chicago and Detroit will provide AT&T the capability to expand their Band 29 supplemental downlink from 5MHz to 10MHz.

Historical Spectrum Data - A Look Back to 2012...MetroPCS, SpectrumCo, Clearwire, and Leap Wireless Mon, Jan 20, 2020

One of the benefits of Allnet Insights' Spectrum Ownership Analysis Tools, is the repository of monthly releases that we have accumulated. With the USA Mobile Carrier Tool we have monthly versions going back to July 2012.  Each of our historical tools details spectrum ownership and the variety of spectrum depth analysis modules that were supported at that time.  

I thought it would be interesting to look back at the spectrum ownership landscape from July 2012.  Looking first at our Spectrum Grid for low band spectrum, you can see that Verizon still holds the 700MHz B block licenses that were sold later to AT&T.  In addition, Verizon also holds the 700MHz A block licenses that were sold to T-Mobile.  

Looking next at the lower mid band spectrum, former licensees like SpectrumCo, Leap Wireless, and MetroPCS still control blocks of AWS-1 and PCS spectrum.  This view of spectrum ownership also allows you to see how Verizon consolidated their AWS-1 spectrum holdings with SpectrumCo's holdings into a 20 MHz block through spectrum license trades with T-Mobile and their MetroPCS licenses.  Today Verizon controls the lower 20 MHz of the AWS-1 band and T-Mobile controls the upper 25 MHz in the New York / New Jersey counties.

Looking at the upper mid band spectrum we first see all of the original WCS spectrum licensees:  Horizon Wi-Com, Nextwave, Sprint, Comcast, and San Diego Gas & Electric.  Clearwire also appears in the upper mid band Spectrum Grid with their 2.5GHz spectrum holdings.

It is interesting then to look at our County Analysis module to see the detail on each carrier's spectrum depth.  It is noteworthy to mention that Verizon has 119 MHz of spectrum in most of the New York / New Jersey counties with AT&T trailing with 91 MHz of spectrum.  Verizon still sits with rough the same amount of spectrum although they replaced all of the 700MHz spectrum they sold to AT&T and T-Mobile with SpectrumCo spectrum and AWS-3 spectrum while AT&T has growth while AT&T has grown their spectrum depth in the same counties to 161 MHz.

Mobile Carrier - Spectrum Ownership Analysis Tool Release for MEXICO Mon, Sep 30, 2019

Allnet Insights & Analytics is excited to announce an expansion of our industry leading spectrum ownership analysis products to cover the Mobile Carrier (600MHz to 3.7GHz) frequency bands for Mexico. We are releasing not only a October 2019 new release, but historical monthly releases going back to June 2016.  The Mobile Carrier Tool not only provides the spectrum allocation details for all of the Mexican Mobile Carrier spectrum but it provides 21 different analysis modules and charts to analyze and compare each wireless carrier's spectrum assets by channel, market, frequency band, band classification, and LTE band class.  Each carrier's licensed population and MHz-POPs values are included as well.

The Mexican Spectrum Grid details the current and future spectrum ownership for each municipio (county).  The municipio areas can be seen on the map below which indicates Ultravision's Broadband Radio (2.5GHz) holdings. 

Below is the Mexican Spectrum Grid for the Mobile Carrier low band spectrum.  All of the 600MHz spectrum is currently controlled by the Federal Telecommunications Institute (IPF) leading up to an early 2020 auction.

5G New Radio (NR) Band Analysis Tue, Jul 23, 2019

In July we expanded the analysis capabilities of our Mobile Carrier and Millimeter Wave - Spectrum Ownership Analysis Tools to include 5G New Radio(NR) Band Analysis for each of the 3GPP supported bandwidths in each US NR band class.

First, in the Mobile Carrier Tool, we are supporting both the uplink and downlink NR bands separately for bands that provide Frequency Division (FDD) operation.  This analysis module outputs the largest channel size (for both uplink and downlink) that a carrier could deploy in their 5G/LTE uplink carrier aggregation scheme or their downlink carrier aggregation scheme. Below in the downlink analysis for AT&T you can see the maximum channel sizes for n12 band spectrum (700MHz A/B/C) versus their n29 band spectrum (700MHz D/E),which is downlink only, and their n14 band spectrum (FirstNet); for each county in the New York Cellular Market Area (CMA).

Similarly, the uplink analysis indicates the maximum uplink channel size for all of the uplink spectrum.

The n41 band spectrum that Sprint's controls (2.5GHz) is seen in the Time Division Duplex(TDD) section.  The analysis tool determines the largest contiguous channel that Sprint can deploy with their leases/owned spectrum including the mid-band segment guard bands.  From the results below, Sprint can configure 80MHz 5G/LTE channels in two New York counties and they can configure a 60MHz channel in one additional New York county.  The remaining counties are limited to carrier aggregation of 20MHz channels. 

In the Millimeter Wave - Spectrum Ownership Analysis Tool, all of the spectrum is configured to Time Division Duplex(TDD) operation.  Below, you can see the different bandwidths that T-Mobile can deploy using their 24GHz or 28GHz spectrum in the New York counties.   Each of the 3GPP standardized bandwidths of 400, 200, 100, and 50MHz are detailed for each spectrum band.

AT&T's Low Band 5G | 700MHz or Cellular Thu, May 09, 2019

 Late last year, AT&T began to discuss refarming their low-band spectrum for 5G, but they didn't indicate which of their low band spectrum blocks would be used.  With some spectrum acquisitions that have been filed over the last 6 months, I believe their plans are becoming more clear.  The 3 blocks of low band spectrum that AT&T controls are 700MHz (A,B, and C channels), 700MHz (FirstNet), and the Cellular (A & B channels). I am going to assume that the FirstNet spectrum is not being considered since it must support public safety networks, leaving the 700MHz and Cellular bands for refarming.  The first indicator, was AT&T's acquisition of FBS 700's spectrum in South Dakota and their acquisition of part of C Spire's 700MHz spectrum in the southeast.  

To see AT&T's total 700MHz spectrum, we used Allnet Insights' Mobile Carrier - Spectrum Ownership Analysis Tool to total AT&T's ownership of the 700MHz A, B, and C channels in each US county.  In the counties where they own all three channels, they could deploy a 15MHz 5G channel.  From the map below, it appears that AT&T would cover most of the US with a 10MHz 5G channel.   

 The next map highlights the counties where AT&T controls both cellular channels (A & B).  In the limited markets where they control both channels (Texas and Florida), they could have a 5G channel size of 20MHz, but for most of the country that would be limited to a 10MHz 5G channel size.  It is important to remember that the areas where AT&T doesn't control any cellular spectrum the bands are controlled by USCellular and/or Verizon, making cellular spectrum acquisitions unlikely.

 Another important way to evaluate the usefulness of each band is to measure the amount of population that can be reach with the licenses in each band.  To evaluate this we used the Licensed POPs Analysis Module from the Mobile Carrier - Spectrum Ownership Analysis Tool.  Since AT&T's 700MHz spectrum covers 44 million addition people compared to AT&T's Cellular spectrum, I believe that AT&T is planning to utilize their 700MHz spectrum for their upcoming Low Band 5G deployments.  This appears to be confirmed by AT&T's recent acquisitions.

Are AT&T and Verizon Leveraging Temporary Licenses for Millimeter 5G? Tue, Apr 02, 2019

Recently in our spectrum transaction tracking we discovered some Millimeter Wave Special Temporary Authority (STA) licenses that AT&T and Verizon have filed in the 39GHz band to conduct wideband testing and for AT&T it appears the spectrum will be used for a market launch later this year.  

To see what is going on, let's look at Verizon and AT&T's ownership of the 39GHz band in the Chicago PEA market (PEA003) with our Spectrum Grid module.  The Spectrum Grid modules is one of nineteen analysis modules in our Millimeter Wave - Spectrum Ownership Analysis Tool.  Below you can see the specific channels that AT&T and Verizon control.  This spectrum is still paired, meaning the lower channels are for uplink and the upper channels are for downlink.  It is apparent that Verizon and AT&T's channels are commingled and that neither carrier can utilize a channel larger than 150MHz (AT&T is limited to 50MHz).  You can see 4 channels that the FCC does control in the lower band, but these are not the channels that AT&T or Verizon requested in their STA.

They each requested channels in the new 37GHz band which will be auctioned later this year.  This spectrum is adjacent to the existing 39GHz licensed bands

The spectrum allocations that Verizon and AT&T have requested in Chicago are indicated below.

This allocation provides both AT&T and Verizon with 400MHz for wideband 5G.  For AT&T, this is likely the spectrum they will utilize for the Chicago market launch announced for later this year.  Verizon likely launched their 5G UWB network using the 28GHz L1 and L2 spectrum seen below, so this 37GHz allotment is likely for network testing.

We have highlighted the effect of the temporary licenses in the Chicago (PEA003).  We noted that AT&T has also requested STA licenses in Raleigh (PEA045), Oklahoma City (PEA039), Charlotte (PEA043) and Philadelphia (PEA006).  Verizon requested STA licenses in New York (PEA001), Cleveland (PEA014), Cincinnati (PEA025), and Tallahassee (PEA072)

39GHz - Auction 103 Reconfiguration Analysis - Number Blocks Tue, Mar 26, 2019

On March 21st, the FCC released a Notice of Procedures describing how existing 39GHz spectrum ownership below will be remapped to the new 39GHz configuration.  We thought it would be beneficial to see how the FCC arrived at their results.

Current Configuration:

Future Configuration:

The procedures the FCC announced will provide a route for the existing 39GHz owners to essentially trade-in their spectrum for vouchers that can be used in Auction 103.  The FCC published a summary of the aggregated holdings data for each of the 39GHz licensees so we decided to use the data from our Millimeter Wave - Spectrum Ownership Analysis Tool to show the underlying calculations.

We are able to use the data from our Millimeter Wave - Spectrum Ownership Analysis Tool to determine the aggregate MHz-POPs value for PEA003 (Chicago).  To find the aggregate MHz-POPs we must first find the MHz-POPs contribution for each of AT&T's licenses (call signs) in the Chicago market.  Below are each of the county MHz-POPs components for each call sign.  We have indicated whether the license covers the entire county or whether it is a partial license in the Full/Partial County column.  The county MHz-POPs component is found by multiplying the bandwidth for each call sign by the county population.  The total aggregate MHz-POPs is the sum of the county MHz-POPs for all of AT&T's licenses.  Using this process, we have found AT&T's aggregate MHz-POPs to by 2,817,188,800 compared to the FCC's results of 2,815,434,000.

The Market MHz-POPs value is found by multiplying the new 39GHz channel size (100MHz) by the total population of the Chicago PEA.  

The next calculation provides the number of blocks that AT&T is authorized to receive in the 39GHz auction by relinquishing their current licenses.  Our analysis indicates that AT&T will start with slightly more than 3 - 100MHz channel blocks in Chicago before the auction starts.

Licensed Spectrum Survey for DAS and Small Cell Implementation Mon, Nov 05, 2018

Two questions for all of the wireless network installers and drive testers:

1)  Where can you get the spectrum assignments for all of the mobile carrier bands with in a county?

2)  How can you determine if the licensed spectrum assignment will change in the near future?

Allnet Insights' Web Spectrum Viewer now includes a Wireless Survey which details the wireless carrier that currently controls each block of Mobile Carrier spectrum (600MHz-2.5GHz) for a selected US county.  In addition, the Wireless Survey indicates whether there are any filed transaction that will move that spectrum to another wireless carrier, as indicated in the Future column.

The output table details the spectrum assignment's,licensees, and bandwidth for each block and is sorted from lowest frequency to highest frequency.  This output table can be exported as a .csv file.

Millimeter Wave - Upper Microwave Flexible Use (Auction Channels) Thu, Aug 30, 2018

New Millimeter Wave Spectrum Bands Thu, Apr 05, 2018

In our last post we were discussing  the next steps for the US millimeter wave spectrum after FiberTower and the FCC settled FiberTower's licensing issues.  As we prepare for a 28GHz auction in November, and a 24GHz auction early next year, let's take a look at how each of the new millimeter wave frequency bands are configured.  Each of these images is taken from our updated Millimeter Wave - Spectrum Ownership Analysis Tool which is now reflecting the new channel band plans for 24GHz, 37GHz, and 47GHz.

24 GHz Spectrum:

In this view we show both the expanded 24GHz band configuration and the old 24GHz configuration. All of the spectrum depth values are calculated from the New 24GHz data. We have left the old 24GHz configuration, so you can continue to see the remaining 24GHz spectrum licenses which will need to be moved over to the New 24GHz by the FCC. The current licenses are licensed for a 40MHz uplink and 40MHz downlink which won't map properly to the new band plan.

37GHz Spectrum:

For the 37/39GHz bands we show the new 37GHz band alongside the reconfigured 39GHz band.  The new 39GHz columns are not populated because the existing spectrum holders will need to be transitioned to the larger/unpaired channels in the new 39GHz plan.  We are providing spectrum depth values for the new 37GHz spectrum and the old 39GHz spectrum.

47GHz Spectrum:

We have added the new 47GHz band configurations to the Spectrum Grid and each of the spectrum depth modules.

PEA Market Analysis:

Our last addition, is a PEA Market Analysis module.  This module displays spectrum depths for each selected carrier using the new FCC Auction market structure.  For the 28GHz auction, you can see the amount of spectrum that will be available in each of the PEAs in the LMDS A (FCC) column on the far right of the chart.
